Get a 'tab group' add on, Simple Tab Groups for Firefox. There is something similar for Chrome but I don't know off the top of my head. I have a different group for any 'context' I often return to (or even a dump of 'researching random thing I may one day come back to'). Then I have one window open and I switch between contexts as needed and pick up from where I left off.
